Assuming a modern SSD/Phone. If the hardware doesn’t physically change and I can’t open it and see 1’s and 0’s, then how does the device know the state before the electricity went off?
In: Technology
At its most basic level, an SSD is a grid of capacitors. That grid stores information by being in a charged state or an uncharged state (1s and 0s as you mention)
Similar to a traditional harddrive, the capacitors are given a location by the cpu bridge, and when it needs to read state, it simply reads out the capacitance.
This is also the reason that SSDs typically last longer if they aren’t used for continuous rewrites.
